Summary
Ivabradine is used to treat heart failure, which is when the heart can't pump blood effectively. It helps improve symptoms like shortness of breath and fatigue by slowing the heart rate. It's used alongside other treatments to enhance their effectiveness.
Ivabradine works by slowing the heart rate, allowing the heart to pump more efficiently. It blocks the "If current" in the heart's pacemaker cells, which control the heart rate, reducing the heart's workload and improving symptoms in heart failure patients.
The usual starting dose of Ivabradine for adults is 5 mg taken twice daily with meals. Your doctor may adjust the dose based on your heart rate and response to the medication, with a maximum recommended dose of 7.5 mg twice daily.
Common adverse effects of Ivabradine include a slow heart rate, known as bradycardia, and visual disturbances like seeing bright spots. These effects are generally mild but should be discussed with a doctor if they occur.
Ivabradine can cause a slow heart rate, leading to dizziness or fatigue. It's not recommended for those with severe liver problems or certain heart rhythm disorders. Avoid grapefruit juice, and consult your doctor about any other medications you're taking to prevent interactions.
